AbstractA series of 3.0Mo/(H beta+gamma-Al2O3) samples with gamma-Al2O3 contents in the range of 0-100% (mass fraction) was studied by means of XRD, NH3-TPD, TPR and BET determinations for characterizing their structures. The H beta zeolite structure in the 3.0Mo/H beta sample can be effectively stabilized by adding some gamma-Al2O3 to H beta zeolite. gamma-Al2O3 mainly favors the formation of polymolybdate or multilayered Mo oxide, while H beta mainly forms the Al-2 (MoO4)(3) species, as evaluated by the TPR, technique. When used as the catalyst for the metathesis of butylene-2 and ethylene to propylene, there exists a close correlation between the specific surface area and stability of the catalyst. The specific surface area of the catalyst shows the maximum when (H beta+gamma-Al2O3) contains 30%gamma-Al2O3, which is in agreement with that of the time needed for the reaction stablization. In the case of maximum surface area, the rate of coke deposition is the minimum.
